Hi Everyone! I've been dealing with this issue for about three months now. There's a Sharp MFP 4050n at a small school that I take care of. And for the last three months every time someone wants to print they have scan to email before it will print. Nothing shows up in the spooler until you scan to email and then they all show up at once. Once you scan to email you have about a 5-10 minute window. I'm unable to ping it even if the printer is awake unless I scan to email first. It has a static IP and is on the same network as the computers. Any help is appreciated, teachers are starting to get frustrated as this is kind of an annoying workaround! Thanks in advance!
